WebFor a first order reaction, this is going to be the units for k, 1/time. For our second order reaction, second order rate law, I'm going to say rate, the exponents add up to 2. I'm going to make it simple on myself and rate equals k[A]². My rate again is Molarity over some unit of time equals K times Molarity, and this time Molarity is squared ... WebIn zero-order reactions, the rate law equation is Rate = k and the unit of rate constant in this case is, mol L − 1 s − 1. For first-order reactions, Rate = k [A]. The constant rate unit, in this case, is s − 1. On the other hand, second-order reactions have a rate law of, Rate = k [A] [B], and rate constant unit of. mol − 1 L s − 1.
